network-operator
Parameters
interface interface-type interface-number: Specifies an interface by its type and number.
instance instance-list: Specifies a space-separated list of up to 10 MSTI items. Each item specifies
an MSTI or a range of MSTIs in the form of instance-id1 [ to instance-id2 ]. The value for instance-id2
must be equal to or greater than the value for instance-id1. The value range for the instance-id
argument is 0 to 4094, and the value 0 represents the CIST.
Usage guidelines
In MSTP mode, the command output is sorted by port name and by MSTI ID on each port.
• If you do not specify an MSTI or port, this command applies to all MSTIs on all ports.
• If you specify a port but not an MSTI, this command applies to all MSTIs on the port.
• If you specify both an MSTI ID and a port, this command applies to the specified MSTI on the
port.
In STP, RSTP, or PVST mode, the command output is sorted by port name.
• If you do not specify a port, this command applies to all ports.
• If you specify a port, this command applies to the port.
Examples
# In MSTP mode, display the BPDU statistics for all MSTIs on GigabitEthernet 1/0/1.
<Sysname> display stp bpdu-statistics interface gigabitethernet 1/0/1
Port: GigabitEthernet1/0/1
